The squirrel-cage magnetic gear has integral corresponding relation between the N stage and the S stage, low transmission precision, and no angular deviation during installation, and this will affect the torque transmission seriously and the performance and the service life and makes the installation inconvenient.
Therefore, it is necessary to develop a high-speed pump having overload self-protection, high transmission accuracy, easy installation, and high transmission efficiency.

By combining the technical scheme, the invention has the following beneficial effects:
the invention provides a magnetic gear disc which comprises a base disc and a plurality of magnets embedded in the base disc and arrayed on the base disc in the circumferential direction. When the number of the magnets mounted on the base plate is odd, the polarities of the magnets on the same side of the base plate are the same; when the number of the magnets mounted on the base plate is even, the polarities of the magnets on the same side of the base plate are the same; or, the polarities of two adjacent magnets on the same side of the substrate are opposite. In short, when the number of magnets is odd, the polarities of the magnets on the same side of the substrate may be N-level or S-level at the same time. When the number of the magnets is even, the polarities of the magnets on the same side of the substrate can be simultaneously N-level or S-level, or the N-level and the S-level can be arranged at intervals.
The two magnetic gear base discs are matched for use to form a magnetic gear assembly, when the number of the magnets on one base disc is odd, the polarities of the magnets on the same side of the base disc are the same, and for matching use, the number of the magnets on the other base disc is odd and the polarities of the magnets on the same side of the base disc are the same. When the number of magnets on one of the base plates is even and the polarities of the magnets on the same side are the same, the number of magnets on the other base plate is set to be even and the polarities of the magnets on the same side of the base plate are the same in order to match with the magnets. When the number of magnets on one of the base plates is even and the polarities of the magnets adjacent to the same side are opposite, the number of magnets on the other base plate is set to be even and the polarities of the magnets adjacent to the same side of the base plate are opposite in order to match with the magnets.
In the use process, two magnetic force gear plates constitute a magnetic force gear assembly, wherein one magnetic force gear plate is connected with the driving end to form a driving plate, the other magnetic force gear plate is connected with the load end to form a driven plate, and due to the magnetic field effect of like poles repelling or opposite poles attracting between the magnets, the driving plate pushes up or pulls the driven plate to realize rotary motion.
Due to the arrangement mode of the magnets, the first driving disc, the driving disc and the driven disc can correspond to the magnets in a one-to-one single-point mode, and therefore transmission precision is high. Secondly, compared with the magnet arrangement mode of the existing squirrel-cage magnetic gear, the squirrel-cage magnetic gear can still ensure normal use when the angle deviation exists between the driving disc and the driven disc, and the normal use of the squirrel-cage magnetic gear is seriously influenced when the angle deviation exists, so that the installation is convenient. Thirdly, because there is the clearance between two magnetic force gear basal discs of magnetic force gear, do not have the friction each other and generate heat in the transmission process, also do not have to choke indisputable problem of generating heat, therefore transmission efficiency is high. Fourthly, when the load end exceeds the approved load, the torque between the driving disk and the driven disk is not enough to drive the driven disk to generate self-slipping, thereby realizing overload self-protection.

The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Embodiment 1 and embodiment 2 are described in detail below with reference to the accompanying drawings:
example 1
The embodiment provides a magnetic gear plate, which comprises a base plate 101, a plurality of magnets 102 embedded in the base plate 101 and arrayed in the circumferential direction of the base plate 101; wherein,
when the number of magnets 102 mounted on the base 101 is odd, the plurality of magnets 102 on the same side of the base 101 have the same polarity (see fig. 1).
When the number of magnets 102 mounted on the base 101 is even, the polarities of the plurality of magnets 102 on the same side of the base 101 are the same; alternatively, the polarities of two adjacent magnets 102 on the same side of the substrate 101 are opposite (see fig. 2).
In the using process, the two magnetic gear disks form a magnetic gear assembly, one magnetic gear disk is connected with the driving end to form a driving disk, the other magnetic gear disk is connected with the load end to form a driven disk, and due to the action of magnetic fields of like poles repelling each other or opposite poles attracting each other between the magnets 102, the driving disk pushes up or pulls the driven disk to realize rotary motion.
Due to the arrangement mode of the magnets 102, the first driving disc, the driving disc and the driven disc can correspond to the magnets 102 one by one in a single point mode, and therefore transmission precision is high. Secondly, compared with the magnet 102 arrangement mode of the existing squirrel-cage magnetic gear, the squirrel-cage magnetic gear can still ensure normal use when the angle deviation exists between the driving disc and the driven disc, and the normal use of the squirrel-cage magnetic gear is seriously influenced when the angle deviation exists, so that the installation is convenient. Thirdly, because a gap is formed between the two magnetic gear base discs 101 of the magnetic gear, the mutual friction heating does not exist in the transmission process, and the problem of the heating of a choke iron does not exist, so the transmission efficiency is high. Fourthly, when the load end exceeds the approved load, the torque between the driving disk and the driven disk is not enough to drive the driven disk to generate self-slipping, thereby realizing overload self-protection.
In an alternative to this embodiment, the magnets 102 are arranged in a racetrack configuration. The racetrack configuration produces the same magnetic field strength and thus the same length of magnetic field as compared to a circular magnet 102 having the same length (diameter), however, the racetrack magnet 102 can provide greater savings in raw materials.
In an alternative embodiment, the central axis of the magnet 102 in the length direction forms an angle with the radial direction of the substrate 101 (see fig. 6). More specifically, a base plate 101 groove for accommodating the magnet 102 is provided on the base plate 101, and a step structure for restricting the passage of the magnet 102 from the base plate 101 groove is provided in a protruding manner along a plane of the base plate 101 toward the inside of the base plate 101 groove at an edge of the base plate 101 groove on one side of the base plate 101. Due to the above-mentioned angle, the groove of the base plate 101 can be set longer and accordingly the magnet 102 can be set longer than the groove of the base plate 101 in the diameter direction of the base plate 101, so that the strength of the magnetic field can be increased and the magnetic torque force can be increased. Specifically, the included angle between the central axis of the base plate 101 in the groove length direction and the radial direction of the base plate 101 is 25-45 degrees, and within the range of the included angle, the magnetic force gear can obtain larger magnetic torque force.
Example 2
The present embodiment provides a magnetic gear assembly including the magnetic gear assembly mentioned in embodiment 1, including a first gear 110 and a second gear 210 used in pairs;
when the number of the magnets 102 mounted on the first gear 110 and/or the second gear 210 is odd, the polarity of the magnets 102 on the same side of the first gear 110 and/or the second gear 210 is the same (see fig. 3).
When the number of the magnets 102 mounted on the first gear 110 and the second gear 210 is even, the polarities of the magnets 102 located on the same side of the first gear 110 and the same side of the second gear 210 are the same, or the polarities of two adjacent magnets 102 located on the same side of the first gear 110 and the same side of the second gear 210 are opposite (see fig. 4).
The embodiment provides a magnetic gear assembly on the basis of embodiment 1, and specifies the matching mode of the magnets 102 on the first gear 110 and the second gear 210 which are matched for use. The first, driving and driven disks may have magnets 102 in a one-to-one single-point correspondence, thereby allowing precise torque transfer. Secondly, compared with the magnet 102 arrangement mode of the existing squirrel-cage magnetic gear, the squirrel-cage magnetic gear can still ensure normal use when the angle deviation exists between the driving disc and the driven disc, and the normal use of the squirrel-cage magnetic gear is seriously influenced when the angle deviation exists, so that the installation is more convenient. Thirdly, because a gap is formed between the two magnetic gear base discs 101 of the magnetic gear, the mutual friction heating and the choking iron heating problem do not exist in the transmission process, so that the transmission efficiency is high (the inventor proves that the transmission efficiency can be as high as 99 percent through tests). Fourthly, when the load end exceeds the approved load, the torque between the driving disk and the driven disk is not enough to drive the driven disk to generate self-slipping, thereby realizing overload self-protection.
The shape and structure of the magnetic gear assembly can be provided in various forms, to name three (please refer to fig. 5):
the first method is as follows: single kit form, in particular:
the magnetic gear assembly comprises a pair of first gears 110 and second gears 210, wherein the first gears 110 and the second gears 210 are oppositely arranged, spaced and staggered;

The first gear set 100 includes first gears a1, a2, and A3; the second gear set 200 includes B1, B2, and B3, with B1 extending partially between a1 and a2, B2 extending partially between a2 and A3, and B3 located outboard of A3. It should be noted that the staggered arrangement described in the second embodiment does not limit the number of the first gears 110 in the first gear set 100 and the number of the second gears 210 in the second gear set 200.

According to the structure, the load end and the drive end are isolated by the magnetic gear assembly consisting of the first gear 110 and the second gear 210, so that vibration transmission between the drive end and the load end is isolated, the noise is low, and the service life of the whole equipment is prolonged.
In an alternative of this embodiment, the above-mentioned driving end may be a driving motor, and the driving motor may be, for example, a three-phase asynchronous motor, and the overall operation performance of the three-phase asynchronous motor is better.
